Bioconversion of Welan Gum from Kitchen Waste by a Two-Step Enzymatic Hydrolysis Pretreatment
Applied Biochemistry and Biotechnology, 2017Kitchen waste (KW) is a worldwide issue, which can lead to environment pollution. Nevertheless, it is also a low-cost and sustainable resource for bio-production. Meanwhile, welan gum (WG) is one kind of the most important exopolysaccharide but with high material cost.

Biomass Conversion and Biorefinery, 2020
Mature coconut husk (MCH) and young coconut husk (YCH) are abundantly generated as a by-product from coconut-based industry, which eventually lead to environmental pollution. However, the lignocellulose content in both types of coconut husk has the potential to be exploited as feedstock by way of biochemical processes through the concept of biorefinery.

One‐Pot Bioconversion of
AbstractThis work reports the one‐pot enzymatic cascade that completely converts l‐arabinose to l‐ribulose using four reactions catalyzed by pyranose 2‐oxidase (P2O), xylose reductase, formate dehydrogenase, and catalase. As wild‐type P2O is specific for the oxidation of six‐carbon sugars, a pool of P2O variants was generated based on rational design ...

α-Arbutin (α-Ab) is a powerful skin whitening agent that blocks epidermal melanin biosynthesis by inhibiting the enzymatic oxidation of tyrosine and L-3,4-dihydroxyphenylalanine (L-DOPA). α-Ab was effectively synthesized from hydroquinone (HQ) by enzymatic biotransformation using amylosucrase (ASase). The ASase gene from Deinococcus geothermalis (DGAS)

Enzymatic Bioconversion for γ-Aminobutyric Acid by Lactobacillus brevis CGMCC No. 3414 Resting Cells
2015In this work, γ-aminobutyric acid (GABA) was prepared by the decarboxylation of l-glutamate via l-glutamate decarboxylase in the resting cells of Lactobacillus brevis CGMCC No. 3414. The influence of cell concentration, cell age, buffer system, reaction time, and substrate concentration were investigated. The optimal composition of bioconversion system
